ASHRAE Standard 188P, Legionellosis: Risk Management for Building Water Systems, could be available for public review this summer.
According to an ASHRAE news release on May 15, Tom Watson, chair of the Standard 188P committee says he is “…optimistic that a fourth public review draft…will be approved and made available during the summer.”
Watson notes this new draft includes some major changes. These include removing Hazard Analysis and Critical Control Points (HACCP) terminology—what once was the cornerstone of the third draft. While the language may be removed some principles of the HACCP process could still be included.
The other notable change includes the addition of “environmental Legionella testing consideration.”
While building industry and other stakeholders have been eagerly awaiting the passage of the standard, Watson cautions against implementing the proposed standard due to more changes that could occur before the official standard is passed.
